Racs are involved in the regulation of important cellular processes including mitogenesis. We found that the E3 ubiquitination ligase subunit Cullin-1 interacts with constitutively active Rac3 but not with wild-type Rac3 in yeast. In mammalian cell lysates, Cullin-1 bound to V12Rac3, effector domain mutants V12L37Rac3 and V12H40Rac3, and insert domain deletion mutant V12Rac3DeltaIns(124-135). Cullin-1 also formed a clearly detectable complex ... [more]
